We were discussing angles and coordinates in the #pico8 Discord and I whipped up this quick demo while we were chatting. It’s a neat demo, and super-neat how easy it was to put it together! The value of a tight feedback loop cannot be understated. gist.github.com/dansanderson/2…

AB and CB are the angles from those lines to the PICO-8 unit circle origin, and ANGLE is ABC (=AB-CB). PICO-8 measures angles in percentage of circumference clockwise (more useful than it sounds!!). pico-8.fandom.com/wiki/Atan2
